SPECIFICATION forming part of Letters Patent No. 560,324, dated May 19,1896.

Application filed June 18, 1894. $erial l o. 514,853. (No model.)

To all w/tom it may concern:

Be it known that I, WILLIAM E. PETTEE, of Boston, in the county ofSuffolk and State of Massachusetts, have invented an Improvement inOan-Labelin g Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representinglike parts.

This invention has for its object toimprove the construction ofcan-labeling machines,bein g especially adapted for applying a label toa cylindrical can, such as ordinarily used for packing fruits and thelike.

My invention comprehends a feeding mechanism for feeding the cansintermittingly, supporting devices for supporting the can in position tobe engaged by the labeling devices, a pair of end clamps adapted to bemoved into engagement with the cans so supported, means for applying anarrow line of paste or other adhesive material lengthwise of the canas,for instance, from end to end thereof-means for giving the can when sopasted a partial revolution to bring its pasted portion beneath one endof a pile of labels supported in such manner that they project over thecan, means for holding the can at rest at such time, a presser forpressing the labels down onto the line of paste previously deposited onthe can-body in order that the lowermost label of the pile may be firmlyattached thereto, said presser also serving to hold the can againstrotation, means for subsequently again engaging the can and giving itone or more complete revolutions, whereby the lowermost label of thepile is withdrawn and wound around the can-body, a wiper brought intoaction just as the can begins to turn to assist in laying the label flatupon the can-body, and means for thereafter disengaging the can andremoving the supporting devices, that the labeled can may be dischargedfrom the machine. One way of holding the labels consists in attachingthem to or upon a pin, from which they may be torn one at a time, or inmaking the pile of labels as a block, they being secured together at oneend only, and adjacent said connected ends of the labels transverseslits are cut extending inward toward each other from each side, so thatthe labels are really connected with an end piece at the middle for ashort distance, so as to become easily detached. In either case theblockor pile of labels is placed in a box especially adapted to receiveit, having supportii'ig-plates, which may be made spring-acting at oneend, adapted to enter the transverse slits of the block, to thereby holdit, providing the block is formed with transverse slits, and having apin if the block is formed as a pile of separate labels, and theopposite end of the box is closed, except for a short distance next thebottom, through which opening a small number of labels may project saytwenty-five, for instance. This box is made so much shorter than thelength of the block or pile of labels that when the labels are placedtherein they will be crowded endwise in such a manner as to bulge up ata point between their ends, except those labels at the bottom of theblock or pile, which project through the end opening of the box, and across-bar is provided above the block or pile of labels, against whichthe bulging portion thereof bears. The bulging portion of the block orpile of labels bearing against the cross-bar serves as a spring to pressthe labels down.

At the upper end of the box containing the block or pile of labels, andwhich I will refer to as the rear end, and occupying a positionsubstantially flush with the bottom thereof, is arranged a pastingdevice adapted to apply a line of paste across the under side of thelowermost label .of the pile at the rear end thereof. The opposite endsof those labels which project through the opening at the front oropposite end of the box oocupya position adjacent to and j u st abovethe can when the latter is in engagement with the end clamps or othermeans employed for rotating it, so that when the pasted portion of thecan is brought into position beneath the forwardlyprojecting end ofthese labels, as it will be by turning said can a partial revolution,the

lowermost label of the pile will be firmly attached thereto by pressingit into contact therewith. Subsequently as the can is rotated thelowermost label is disconnected or detached and withdrawn from the boxand wrapped around the can, being laid flat thereon by means of thewiper, and as the can makes a complete revolution the rear pasted end ofthe label will overlap the opposite end thereof and will therefore befirmly secured in place. Hence the two ends of the label are secured,one to the can-bod y and the other to the opposite end of the label.

The main framework of the machine consists of a declining bed A,supported by or upon legs B. Upon the bed A are arranged two pairs oflongitudinal strips a a in line with each other, the strips of each pairbeing located a short distance apart to form between them a guideway ofsuitable width for the can and the two pairs being separated a shortdistance to receive between them the labeling devices. One of said pairsof strips serves to guide the can to the labeling devices and the otherto direct the course of the can after leaving the labeling devices.

Near the upper end of the bed A a feedwheel is journaled, it beingherein shown as consisting of two flat end pieces a a, secured to ashaft a and having several semicircular recesses cut in theirperipheries to receive the cans, six such recesses beingherein shown.The shaft a has its bearings below the bed A, and the end pieces aproject up through the bed, which is slotted, as at a, to accommodatethem, so that the bottoms of the semicircular recesses in said endpieces successively occupy a position substantially flush with thesurface of the bed A, so that the cans while resting upon said bed, asshown in Fig. 3, may roll down toward the labeling devices by gravity. Aratchet-wheel d is secured to the shaft a which is engaged by one end ofa lever (H, (see Fig. 3,) pivoted at a to a lug a, depending from theunder side of the bed A, the opposite end of said lever being acted uponby a cam a, secured to the main actuating or driving shaft C. The 10-ver a is held pressed into engagement with the ratchet-wheel a by meansof a spring a secured to the under side of the bed.

At each revolution of the main shaft (1 the lever a" is raised for ashort interval of time to permit the feed-wheel a a to turn one step,which it will do at such time by the weight of the cans upon it, so asto let off or release one can, which is the endmost can of the series.As the endmost can is released it rolls along the bed A between theguide-strips (t a until it strikes a stop or can-supportin g device I),(see Figs. 1. and 14,) herein shown as an upright curved arm, pivoted atb to a lug b on the under side of the bed A and adapted to be raisedthrough a slot in the bed and held up in its vertical or elevatedposition, so as to stop the progress of the can, by means of a lever If,pivoted at Z)" and acted upon by a cam Z2 which is also secured to themain driving-shaft C.

The lever b has a projection b" thereon, which serves as a stop orabutment against which the lever b bears, and the cam b is arranged tohold said lever 11 in its elevated position for a certain period of timeand to thereafter permit said lever to retreat or drop into thedotted-line position shown in Fig. 14, in order that the lever b maylikewise drop into the dotted line position therein shown and leave theupper surface of the bed unobstructed for the free escape or dischargeof the can.

\Vhen the can strikes the stop I), itis liable to rebound, and henceIhave herein provided two spring-acting arms 0 0, arranged at each sideof the path of progress of the can above the feed-wheel, (see Figs. (3,8, and 0,) said arms converging toward each other. These arms arepivotally supported upon pins 0, rising from the bed A at points justoutside of the guide-ribs a a, so that they are separated suflicientlyat the rear end of the machine for the entrance between them of the can,and the opposite ends of said arms have right-angular portions 0 slottedas at c, to receive pins 0, likewise rising from the bed A like the pins0, said pins 0 serving as guidepins for the arms. Springs 0 are placedin the slots of the arms bearing against the pins 0, the tendency ofwhich is to throw the arms inward toward each other, as best shown inFig. 6. As the can rolls along its guideway the arms 0 c are graduallyspread until the can strikes the support Z1, at which time it passes bythe ends of the arms, permitting them to be restored to their normalposition, and at such time they will serve as back-stops to preventrebounding of the can. Two end clamps are provided which are adapted tobe brought into engagement with the ends of the can when it is so heldby the stop or other supporting device I), said clamps each consistingof a circular recessed plate (Z to embrace the end of a large-sized can,having upon its rear side several pins (1, which pass loosely throughholes in a plate (1 said pins being provided at their outer ends withnuts ITO (Z and a rubber pad or block or other form of spring isinterposed between said plates d (:1 acting to press the plate clinwardly or away from the plate d such movement being limited by thenuts (1 As the pins cl work freely in the plate (Z the spring (1 permitsthe plate cl to yield to compensate for any slight differences in thelengths of the cans.

For small-sized cans an auxiliary recessed plate d (see Fig. 5) will besecured to the interior of the plate (Z. I

Each end clamp, by its plate 61 is secured to a short shaft (1 havingits bearings in suitable brackets d, secured to the bed A, said shaftbeing movable endwise in said brackets, and each shaft (1 has a pinion dfixed thereon, which is engaged and driven by a toothed gear (i securedto the ends of the main driving-shaft C. As the main shaft 0 is rotatedthe shafts d (Pare both rotated,

Secured to the inner face of each toothed gear (1 and extending for apart of the way around it, is a cam (Z which engages a hub '(Z securedto the shaft (1 said cams acting 25 upon said hubs to move the shafts dinwardly sufficiently for the clamping-plates to embrace and firmlyengage the ends of the can, and thereafter permitting said shafts toretreat a short distance, that the can maybe released so as to be heldagainst rotation, yet held in its proper position to receive correctlyupon it the label, and permitting said clamping-plates tocontinuouslyrevolve, and thereafter again moving the shafts d inwardly,that the clamping-plates may again engage and rotate the cam. A spring(I encircles each shaft (1 the tendency of which is to throw itoutwardly.

In order that the cams 61 may operate or act upon the shafts d in thismanner, they are each made with two projecting flat faces with areducedor cut-away portion (1 between them, the foremost projecting face actingto throw the end-clamping plates into engagement with the ends of thecan, the reduced portion (Z permitting the end-clamping plates toretreat sufficiently to release the can and continue to rotate withoutrotating the can, yet holding the can from moving endwise, or frommoving out of its proper position, that it may receive upon it correctlythe label, and the following projecting face again acting to throw theend-clamping plates intoengagement with and thereby rotating the can.

A pasting device is arranged beneath and just at the rear of the centerof the can, (see Figs. 3, 15, 16, and 17,) it consisting of arectangular receptacle 6 open at the top and containing felt e or othermaterial, said receptacle being contained within or supported by across-piece e movable in vertical guideways formed in the sides of arecess formed in the'framework and resting upon the outer end a of alever e, pivoted at e to a lug beneath the bed, said lever being actedupon by a cam e secured to the main drivingshaft C. A tube 6 connectswith the receptacle e of the pasting device and a flexible pipe (notshown in the drawings)leads from a paste-reservoir, which is situated atany convenient place, and connects it with said tube 6 the paste beingthus carried to the receptacle and absorbed by the felt strip 6.

The pasting device works vertically in or through an opening in the bedA, and as it must be moved quickly I have herein formed on the lever e aprojection e, which is engaged by the cam or projection 6 moving saidlever quickly as the cam 6 passes by or over said projection, therebythrowing the pasting device up against the can held by the end-clampingplates. This pasting device is designed to apply to or deposit upon thecanbody, from end to end thereof, a narrow line of paste just after oras soon as the can has been engaged by the end-clampin g plates, and asthe said clamping-plates are continuously rotated consequently the can,as soon as engaged thereby, will begin to rotate, so it is necessary forthe pasting device to operate quickly to prevent applying the paste totoo great a surface. Yet if deemed necessary the paste may be applied tothe entire surface of the can. Just as soon as the end-clamping platesare thrown into engagement with the can, and the pasting device hasoperated to deposit upon the can-body a' line of paste, the can is givena partial revolution, so as to bring the line of paste so deposited uponthe can-body at the upper side and beneath the pile of labels.

The labels are contained in a quadrangular box supported above the bedA, as shown in Figs. 1, 2, and 6, said box being herein shown ascomposed of two parallel side walls f f, secured to cross-pieces f f,arranged to slide on bars f f*, or they may be rigidly secured to saidbars, a bottom composed of slats f f", likewise supported upon saidcrosspieces f f, a pin f at the rear end, and an end wall f at theopposite end extending from at or near the top of the box to a'pointnear to but not touching the bottom, so that an opening f is presentedat the front end of the box. (See Figs. 7 and 12.) The front end wall fis arranged slightly oblique, being extended in toward the center of thebox, except at its lower end, which is extended outwardly. A rod f 13extends transversely across the upper part of the label-holder and issecured to its side walls f. The cross-pieces f f are slotted, as at fto receive the bolts f", by means of which the label-box is securedthereto, such construction giving the box a transverse adjustment. Theside bars f f upon which said cross-bars are mounted, are formed at eachend with ears f having holes through them which receive the pins 0 c 0 cand the upper ends of all of said pins are screw-threaded and receivenuts f there being a nut above and below each ear f so.

that by turning said nuts said side bars may be adjusted vertically, tothereby vertically adjust the label-box.

At the bottom of the rear end of the label box or holder a narrowpaste-box 7b is provided, extending from side to side of the box, itconsisting of a flat perforated receptacle h, adapted to contain a pieceof felt and placed upon or covering a thin paste-receiver 7L2, having aninlet 7& at one end for the paste, and the perforated felted receiver,becoming saturated with the paste, deposits a narrow line of the sameupon the under side of the lowermost label of the pile contained withinthe holder and resting upon said perforated paste-box h.

The separate labels are placed in the box beneath the transverse bar fand upon the pin f from which they are detached one at a time, beingtaken from the bottom of the pile, and they are made longer than theboX,

so as to be crowded therein endwise, bulging up at the central portion,as shown in Fig. 12, the end of the pile being directed downward by saidtransverse bar f, so as to bear against the lower oblique oroutwardly-extended portion of the end wall f, and the bulge thus givento the pile serves as a spring to thrust the labels forward endwise. Asthe bulged labels tend to straighten out the said oblique oroutwardly-extended lower edge of the front end wall f directs theirfront edges down toward the opening 1, and the bottom label or labelsFwill be thus caused to project ashort distance through said opening inposition to be pasted. The lowermost labels of the pile project throughthe opening f at the bottom of the front end of the box just above thecan and beneath a presser-block g, tobe described.

The label-box is adapted to be moved longitudinally on. the side bars ff by means of curved arms 0 0, attached to a verticallymoving part ofthe machine and acting upon friction rolls or pins 0' 0 upon theopposite sides of the label boX or holder. hen said vertically-movingpart descends, the labelbox will be advanced a short distance againstthe tension of the springs 0 0 after which said box is restored to itsnormal position by said springs. This longitudinal movement is given tothe label box for the purpose of preventing any strain upon the labelwhich might occur incident to the action of the presser g, and it alsoassists in detaching the labels-as, for instance, when the presser gdescends, were it not for the yielding action of the label-box greatstrain would be brought upon the labels, which would detach a number ata time from the pin f When the label has been attached to the can or tothe line of paste deposited thereon, a sudden rearward movement of thelabel-box assists in detaching said label from the pin f. Thepresser-block g is secured to the under side of a cross-bar g, adaptedto slide vertically between or upon vertical uprights 9 rising I for.

the uprights g g from the bed A, they serving as guides there- Thecross-bar g has secured to its upper side two or more pins which pass upthrough a cross-bar g similar to g, said pins being screw-threaded attheir upper ends and provided with nuts 9 .Springs g encircle the pins gbetween the cross-bars g g exerting their pressure upon or against saidlower cross-bar. The lower cross-bar g is thus made to yield vertically.The upper cross-bar g is securedto the lower end of a screw-rod g",which passes up through a nut 9 secured to a movable cross'head g", andalso loosely through a stationary cross-head g", the latter beingsecured to the upper ends of The cross-head g is made with holes at theend which receive the uprights g g in order that it may slide vertically011 said uprights as guides, and when so moved the nut g and cooperatingscrew-rod g and other attached parts move with it.

At each end of the movable cross-head g" a depending rod is looselyconnected,

which extends down at each side of the machine, (see Figs. 1 and 5,) thelower ends thereof being bent or formed with right-angular extensions 9which are engaged by cams g secured to or upon themain driving-shaft 0.As the shaft 0 is rotated, the cams 9 act 1 to depress the cross-headg", and consequently ;the prcsser-block g is brought down upon or 1against the can.

To elevate the cross-head 9* after the cams 9 have ceased to act, I haveerected upon said cross-head two vertical pins 1 which extend up throughholes in the stationary cross-head g having at their upper ends nuts gand spiral springs g encircle said pins, bearing at their lower endsagainst the cross-head and at their upper ends against the nuts. Theparts are so timed that the cams 9 act to depress the presser-block gjust as the reduced portions (Z of the cams d are brought into positionto permit the end-clamping plates to release the can, so as to press thelabels down upon the can-body at that part thereof whereon the line ofpaste has previously been deposited. Another presser-block or pad 1',having a yielding surface i, is located directly beneath the can, i (seeFigs. 3, 19, and 20,) which is adapted to slide vertically in guidewaysprovided on the interior of the opening beneath the can, and to raisesaid presser-block cams i 2' are secured to the main driving-shaft C,which are brought into position to raise the block just as the block gis depressed, so that the can will be firmly held between them. \Vhilethe can is thus held the end clamps which have been disengaged therefromcontinue to re- Volve. As the main driving-shaftC continues to advancethe projecting portion of the cam .61 again acts to move the end clampsinto engagement with the can, and thus the can becomes again engaged asthe presser-blocks 1 g and 'i retreat. The label at such time will befirmly attached to the can-body at the point whereon the line of pastewas deposited. As the main shaft C continues to revolve the can will begiven one, or it may be more, revolutions, winding the label around thecan-body, and its opposite end, which receives upon its under side aline of paste from the paste-box, will overlap the pasted end of thelabel and become firmly attached thereto.

A wiper m, made as a flexible plate as a piece of rubber, for instanceissecured to a cross-head m, adjustably secured to two upright rods mwhich extend down through an opening or openings inthe machine, thelower ends of said rods being formed with right-angular extensions madapted to be engaged by hooks m formed on arms m pivoted at m to lugs mthe outer ends of said arms being acted upon by cams m secured tothe'main driving-shaft C. By means of these cams the wiper m isdepressed or brought into contact with the can, so as to wipe or smooththe label thereon as the can is rotated. Spiral springs m encircle therods m and act to raise the wiper when the cams cease to act.

The several groups of mechanism herein shown and described are or may bemade adj ustable for different sizes of cans, and also may be somewhatdifferently constructed as to detail, without departing from thisinvention.

Instead of placing the labels in the labelbox on the pin f the pile oflabels X may be slitted transversely from the opposite edges inward,almost meeting, as shown at X in Fig. 22, and the label-box may beprovided with two inwardly-projecting spring-plates Z, (see Fig. 21,)adapted to enter the slits in the labels and thereby hold the pile oflabels.

. ,The labels thus held may be easily detached.
